Desenvolvimento de um protótipo de medidor de energia elétrica para aplicação em redes elétricas inteligentes.

Abstract

Due to the increasing changes in the Electric Power System, new possibilities for the advancement of monitoring technologies have emerged and the concepts and methodologies brought by the smart electric grids have originated new tools and information for the concessionaires. For the implementation of an intelligent network, it is necessary to modernize the entire system, especially the measurement and monitoring techniques on the operation and operation of the network for access to more accurate and real-time data for all involved, enabling decision-making faster and thus increasing operational efficiency. In this context, the objective of this project is the study and development of a three-phase bidirectional electricity meter that makes it possible for the concessionaire to monitor, in real time, the electricity consumption of its consumer units. For this purpose, research was carried out to identify the operational characteristics and functionalities of smart meters in order to define the requirements of the system and the tools that are part of the project. To this end, the objective of this project was successfully achieved through the development of meter sensing systems using the ACS758 sensor and voltage transformers that allow the reading of electrical quantities, monitoring and communication through microcontroller ESP32, which enables the sending of data to be stored in a local database and displayed in a WEB interface. Based on the information gathered in the body of the document, a summary is made at the end of the work on the gain for the concessionaire by implementing a system such as the one proposed.
